ABSTRACT

The compression function and/or quantization function can be adaptively and/or otherwise selected based on various criteria, such as the amount of data being transmitted, whether the data corresponds to reference signals or other data, the network architecture (e.g., digital beamforming or hybrid beamforming) in use, and so on.

RELATED APPLICATION

The subject patent application is a continuation of, and claims priority to, U.S. patent application Ser. No. 15/876,842, filed Jan. 22, 2018, and entitled “COMPRESSION OF RADIO SIGNALS WITH ADAPTIVE MAPPING,” the entirety of which application is hereby incorporated by reference herein.

TECHNICAL FIELD

The subject application is related to wireless communication systems, and, for example, to adaptively compressing data communications between base station components in a wireless communication system.

BACKGROUND

In new radio, sometimes referred to as 5G, cellular networks are being designed with cellular base stations having a split RAN (radio access network) architecture. In general, a split architecture is one in which the analogue radio front-end, referred to as the radio units, and the digital baseband processor, referred to as a central unit, are not co-located components. Instead, these components are connected via high speed serial cables. For example, multiple radio units comprising antennas, analog-to-digital converters (ADC)/digitizers, and digital-to-analog converters (DAC) may be mounted on a tower, with the central unit located at the base of the tower, where there is a power source, etc.

In new radio, sometimes referred to as 5G, cellular networks are being designed to achieve high data-rate requirements by using large communication bandwidth. However, the throughput needed for the high speed serial cables can be a limiting factor in the amount of data being communicated.

DETAILED DESCRIPTION

Briefly, one or more aspects of the technology described herein are generally directed towards compressing data communicated over the serial link (or IP network, etc.) between a radio unit and a central unit. For uplink transmissions from a user equipment received at a radio unit, compression and quantization before sending to the central unit via the serial link provide for increased throughput over the link. The compression and/or quantization may be adaptively controlled, e.g., data from a high bandwidth user (as estimated) may be compressed and/or quantized differently relative to the data from a low bandwidth user.

For downlink transmissions from the central unit to the radio unit for transmitting to the user equipment, adaptive compression and/or quantization provides for increased throughput over the serial link in the opposite direction. The compression and/or quantization may be adaptively controlled. While it is feasible to estimate data to send, the scheduler can provide more specific information that is used to adapt compression and/or quantization.

Still further, reference signals are sent from the central unit to the radio unit for transmitting to the user equipment. In general, because estimating the channel is relatively more important, the compression of reference signals can use a different compression function, e.g., one in which more resolution is used when compressing reference signals compared to compressing data.

In another embodiment, the compression function can be different based on the network architecture. For example, the number of bits used in compression with hybrid beamforming can be different than the number of bits used in compression with digital beamforming.

In some embodiments the non-limiting term “radio network node” or simply “network node,” “radio network device or simply “network device” is used herein. These terms may be used interchangeably, and refer to any type of network node that serves user equipment and/or connected to other network node or network element or any radio node from where user equipment receives signal. Examples of radio network nodes are Node B, base station (BS), multi-standard radio (MSR) node such as MSR BS, gNodeB, eNode B, network controller, radio network controller (RNC), base station controller (BSC), relay, donor node controlling relay, base transceiver station (BTS), access point (AP), transmission points, transmission nodes, RRU, RRH, nodes in distributed antenna system (DAS) etc.

In the split architecture for a cellular base station, a “radio unit” (or a “radio device,” which comprises at least one radio unit) is coupled to the “central unit” (or “central device,” which comprises at least one central unit) via a communications link, typically a high-speed serial cable. As is understood, in the uplink direction, although the base station receives data from the user equipment, with respect to the (e.g., serial) link the radio device is the “sender” or “transmitter” to the central unit, which is the “receiver.” Conversely, in the downlink direction, although the base station transmits data to the user equipment, with respect to the (e.g., serial) link the central device is the “sender” or “transmitter” to the radio device, which is the “receiver.”

In some embodiments the non-limiting term user equipment (UE) is used. It refers to any type of wireless device that communicates with a radio network node in a cellular or mobile communication system. Examples of user equipment are target device, device to device (D2D) user equipment, machine type user equipment or user equipment capable of machine to machine (M2M) communication, PDA, Tablet, mobile terminals, smart phone, laptop embedded equipped (LEE), laptop mounted equipment (LME), USB dongles etc.

FIG. 1 illustrates an example wireless communication system 100 in accordance with various aspects and embodiments of the subject technology. In one or more embodiments, the system 100 can comprise one or more user equipment UEs 102(1)-102(n).

In various embodiments, the system 100 is or comprises a wireless communication network serviced by one or more wireless communication network providers. In example embodiments, a UE 102 can be communicatively coupled to the wireless communication network via a network device 104 (e.g., network node). The network device 104 can communicate with the user equipment (UE) 102, thus providing connectivity between the UE and the wider cellular network.

In example implementations, each UE 102 such as the UE 102(1) is able to send and/or receive communication data via a wireless link to the network device 104. The dashed arrow lines from the network device 104 to the UE 102 represent downlink (DL) communications and the solid arrow lines from the UE 102 to the network devices 104 represents uplink (UL) communications.

The system 100 can further include one or more communication service provider networks 106 that facilitate providing wireless communication services to various user equipment, including UEs 102(1)-102(n), via the network device 104 and/or various additional network devices (not shown) included in the one or more communication service provider networks 106. The one or more communication service provider networks 106 can include various types of disparate networks, including but not limited to: cellular networks, femto networks, picocell networks, microcell networks, internet protocol (IP) networks Wi-Fi service networks, broadband service network, enterprise networks, cloud based networks, and the like. For example, in at least one implementation, system 100 can be or include a large scale wireless communication network that spans various geographic areas. According to this implementation, the one or more communication service provider networks 106 can be or include the wireless communication network and/or various additional devices and components of the wireless communication network (e.g., additional network devices and cell, additional UEs, network server devices, etc.).

The network device 104 can be connected to the one or more communication service provider networks 106 via one or more backhaul links 108. For example, the one or more backhaul links 108 can comprise wired link components, such as a T1/E1 phone line, a digital subscriber line (DSL) (e.g., either synchronous or asynchronous), an asymmetric DSL (ADSL), an optical fiber backbone, a coaxial cable, and the like. The one or more backhaul links 108 can also include wireless link components, such as but not limited to, line-of-sight (LOS) or non-LOS links which can include terrestrial air-interfaces or deep space links (e.g., satellite communication links for navigation).

Some embodiments are described in particular for 5G new radio systems. The embodiments are however applicable to any radio access technology (RAT) or multi-RAT system where the user equipment operates using multiple carriers e.g. LTE FDD/TDD, WCMDA/HSPA, GSM/GERAN, Wi Fi, WLAN, WiMax, CDMA2000 etc.

The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the user equipment. The term carrier aggregation (CA) is also called (e.g. interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception.

The wireless communication system 100 can employ various cellular systems, technologies, and modulation schemes to facilitate wireless radio communications between devices (e.g., the UE 102 and the network device 104). While example embodiments might be described for 5G new radio (NR) systems, the embodiments can be applicable to any radio access technology (RAT) or multi-RAT system where the UE operates using multiple carriers e.g. LTE FDD/TDD, GSM/GERAN, CDMA2000 etc. For example, the system 100 can operate in accordance with global system for mobile communications (GSM), universal mobile telecommunications service (UMTS), long term evolution (LTE), LTE frequency division duplexing (LTE FDD, LTE time division duplexing (TDD), high speed packet access (HSPA), code division multiple access (CDMA), wideband CDMA (WCMDA), CDMA2000, time division multiple access (TDMA), frequency division multiple access (FDMA), multi-carrier code division multiple access (MC-CDMA), single-carrier code division multiple access (SC-CDMA), single-carrier FDMA (SC-FDMA), orthogonal frequency division multiplexing (OFDM), discrete Fourier transform spread OFDM (DFT-spread OFDM) single carrier FDMA (SC-FDMA), Filter bank based multi-carrier (FBMC), zero tail DFT-spread-OFDM (ZT DFT-s-OFDM), generalized frequency division multiplexing (GFDM), fixed mobile convergence (FMC), universal fixed mobile convergence (UFMC), unique word OFDM (UW-OFDM), unique word DFT-spread OFDM (UW DFT-Spread-OFDM), cyclic prefix OFDM CP-OFDM, resource-block-filtered OFDM, Wi Fi, WLAN, WiMax, and the like. However, various features and functionalities of system 100 are particularly described wherein the devices (e.g., the UEs 102 and the network device 104) of system 100 are configured to communicate wireless signals using one or more multi carrier modulation schemes, wherein data symbols can be transmitted simultaneously over multiple frequency subcarriers (e.g., OFDM, CP-OFDM, DFT-spread OFMD, UFMC, FMBC, etc.). The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the UE. The term carrier aggregation (CA) is also called (e.g. interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception. Note that some embodiments are also applicable for Multi RAB (radio bearers) on some carriers (that is data plus speech is simultaneously scheduled).

In various embodiments, the system 100 can be configured to provide and employ 5G wireless networking features and functionalities. With 5G networks that may use waveforms that split the bandwidth into several sub bands, different types of services can be accommodated in different sub bands with the most suitable waveform and numerology, leading to improved spectrum utilization for 5G networks. Notwithstanding, in the mmWave spectrum, the millimeter waves have shorter wavelengths relative to other communications waves, whereby mmWave signals can experience severe path loss, penetration loss, and fading. However, the shorter wavelength at mmWave frequencies also allows more antennas to be packed in the same physical dimension, which allows for large-scale spatial multiplexing and highly directional beamforming.

Performance can be improved if both the transmitter and the receiver are equipped with multiple antennas. Multi-antenna techniques can significantly increase the data rates and reliability of a wireless communication system. The use of multiple input multiple output (MIMO) techniques, which was introduced in the third-generation partnership project (3GPP) and has been in use (including with LTE), is a multi-antenna technique that can improve the spectral efficiency of transmissions, thereby significantly boosting the overall data carrying capacity of wireless systems. The use of multiple-input multiple-output (MIMO) techniques can improve mmWave communications; MIMO can be used for achieving diversity gain, spatial multiplexing gain and beamforming gain.

Note that using multi-antennas does not always mean that MIMO is being used. For example, a configuration can have two downlink antennas, and these two antennas can be used in various ways. In addition to using the antennas in a 2×2 MIMO scheme, the two antennas can also be used in a diversity configuration rather than MIMO configuration. Even with multiple antennas, a particular scheme might only use one of the antennas (e.g., LTE specification's transmission mode 1, which uses a single transmission antenna and a single receive antenna). Or, only one antenna can be used, with various different multiplexing, precoding methods etc.

The MIMO technique uses a commonly known notation (M×N) to represent MIMO configuration in terms number of transmit (M) and receive antennas (N) on one end of the transmission system. The common MIMO configurations used for various technologies are: (2×1), (1×2), (2×2), (4×2), (8×2) and (2×4), (4×4), (8×4). The configurations represented by (2×1) and (1×2) are special cases of MIMO known as transmit diversity (or spatial diversity) and receive diversity. In addition to transmit diversity (or spatial diversity) and receive diversity, other techniques such as spatial multiplexing (comprising both open-loop and closed-loop), beamforming, and codebook-based precoding can also be used to address issues such as efficiency, interference, and range.

In FIG. 1, as described herein, the network node has a split architecture comprising a central unit 110 and a number of radio units 112. The network node, via the central unit and a radio unit, is configured to provide reference signals and data 114 to a user equipment (e.g., 102(1)), which returns Channel Status Information (CSI) and data to the network node 104.

For inter-node communications between the radio unit and the central unit, in a split RAN architecture, the amount of unidirectional throughput for such radios can be expressed as

T=2NBM

where T is the throughput in bits/sec, N is the number of antennas, B is the signal bandwidth in Hz, and M is the number of bits used to quantized each of the in-phase and quadrature signals. By way of example, for a typical 5G scenario with 8 antennas and 200 MHz bandwidth, the throughput is equal to 400*M megabytes/sec. A typical ADC uses 16 bits for quantization, yielding 6.4 gigabytes/sec. From this analysis, while the number of antennas and the bandwidth are decided by the standardization and performance requirements, the number of effective bits used to quantize the I and Q signals can yield significant reduction in throughput. The technology described herein provides a scheme to quantize the I and Q signals to reduce the throughput yet still meet signal integrity requirements. To this end, the communications between the radio units and the central units may be compressed, including via different compression functions adapted for different criteria.

FIG. 2 initially shows a block diagram representing uplink transmissions received at an antenna 222 of a radio unit 212 of a network node comprising a base station 204. As can be seen, the analog data x is compressed by compression function 224, quantized by quantizer 226 before being sent over the serial link to the central unit. Note that along with the compressed, quantized data x_(C), the compression parameter vector P and quantization parameter M are sent to the central unit in this example, because these can vary as adapted for different data being transmitted.

In one example, a finite set of real numbers {x₁, x₂, . . . x_(K)}, (x_(i)∈S∀i) is considered for quantization. A bijective mapping function is established at both the compressor and the decompressor (decompression function 228). The compression mapping function 224 is denoted by ƒ(P;⋅): S→[−1,1), where P is the parameter vector that defines this function. The decompression mapping is denoted by g(P;⋅): [−1,1)→S, such that g(P; ƒ(P;x)=x∀x∈S. A uniform quantizer 226 can be represented as if Q(M;x): [−1,1)→[−1,1) where M is the number of bits used for quantization.

${Q\left( {M;x} \right)} = {\frac{\left\lfloor {2^{M - 1}x} \right\rfloor}{2^{M - 1}}.}$

The selection of compression and decompression function depends on individual embodiments, and can be lossy or lossless. For example, one embodiment may use log companding, e.g., A-law mapping, such that

${f\left( {A;x} \right)} = {{{sgn}(x)}\left\{ \begin{matrix} {\frac{A{x}}{1 + {\log (A)}},\ {{x} < \frac{1}{A}}} \\ {\frac{1 + {\log \left( {A{x}} \right)}}{1 + {\log (A)}},{\frac{1}{A} \leq x < 1}} \end{matrix} \right.}$

where P=A, e.g., A can be any number from 1 to infinity. Note that the compression parameter vector P is a generalized vector that can be based on a single parameter A or based on more parameters, e.g., A, B and C.

It should be noted that different compression and decompression functions may be present at the sender and the receiver and chosen based on any criterion. For example, compression function 1 or compression function 2 may be available at the sender, and as long as the sender communicates (or the receiver can otherwise determine) which one is being used, the receiver can select the counterpart decompression function.

The estimation (block 228) of the parameter vector P and the quantization parameter M are selective, and can be adapted based on one or more different criteria. The block size K used during compression is also selectable. For example, some users need a lot of throughput, some users need far less. For example, for lower throughput, fewer compression bits may be used, whereas for high throughput, more compression bits may be used. Note that for downlink communications, the scheduler knows in advance what throughput is needed, the type of data and so on, and thus scheduler assisted compression and/or quantization can be used.

FIGS. 3 and 4 show downlink counterpart diagrams in which the central unit 210 is the sender to the remote unit 212. As can be seen, data can be compressed at the central unit and decompressed/dequantized at the remote unit 212. In FIG. 3, the compression vector is estimated, whereas in FIG. 4, the compression vector is based on information known to the scheduler.

Note that for downlink data transmission, reference signals are used to estimate the channel between the base station and the user equipment. In general, because estimating the channel is relatively important for decoding data, reference signals can use a different compression function, e.g., one in which more resolution is used for reference signals compared to the compression function used for data. For example, a 4-bit compressor may be used for data, with 8-bit or 16-bit compression is used for reference signals.

Note that 5G standards define various reference signals such as CSI-RS, (channel state information reference signals), DMRS (demodulation reference signals), PTRS (phase-tracking reference signals), SRS (sounding reference signals), etc. In one embodiment represented in FIG. 5, the reference signals are compressed by compression selection logic 550 of the central unit 510 with the same compression function. The data is compressed with a different (e.g., lower resolution) compression function.

In contrast, as represented in the alternative embodiment of FIG. 6, the demodulation reference signal uses a still higher resolution (more robust) compression function relative to the other reference signals and data. This alternative is represented by compression selection logic 650 of a central unit 610 Note that the other reference signals may use the same compression function as used for the data, or different compression functions for the other reference signals and data (as in FIG. 6).

It should be understood that data returned from the user equipment may likewise be compressed differently based on its purpose. For example, the CSI report from the user equipment received at the radio unit may be compressed differently relative to how other data is compressed, before sending to the central unit.

Turning to another aspect, the compression function can different based on the network architecture. For example, in downlink transmission, if hybrid beamforming is used, then the number of bits for compression can be Y, whereas with digital beamforming, the number of bits for compression is different compared to Y; (in general it is less than Y). Hence if the network knows the architecture, the network can adapt the number of bits for compression. Note that same procedure applies for de-compression.

FIG. 7 represents hybrid beamforming, while FIG. 8 represents full digital beamforming. In general, baseband precoding includes both P1 and P2 as shown inside the dashed box 802 of FIG. 8. The matrix product of P1×P2 is the effective precoder; P1×P2 is fixed within a scheduling granularity (L PRB×M symbols). Note that P1 is based on explicit feedback (e.g. PMI), however P1 can be different from PMI e.g. for MU-MIMO, Codebook restriction, Nonlinear precoding e.g., THP. P1 is user equipment specific and P1 can be sub-band or wide-band.

For RF beamforming, in general analog beamforming is represented as the stage P3 (FIG. 7). The actual weights are based on a given implementation, but in general the index is obtained via beam management procedures for NR. Note that in the hybrid beamforming of FIG. 7, with respect to the wide RF beams, in LTE P3 is fixed; in NR, P3 is obtained via beam management procedures and in NR, P3 is user equipment specific. P3 is always wideband and the same across all CC.

For full digital beamforming, in TDD, P2 is based on TDD Reciprocity, and in FDD, P2 is based on CRI (CSI-RS feedback). FDD P2 can also be based on reciprocity. P2 can be UE specific or cell specific, which depends on a given implementation. P2 can be sub-band or wideband.

FIG. 9 represents a graph of throughput versus compression level simulation results for hybrid beamforming. FIG. 10 represents a graph of throughput versus compression for a downlink analysis with all digital beamforming.

Operation 1102 represents receiving data, and operation 1104 represents estimating the data or obtaining information regarding the data from which compression/quantization parameters may be selected. Operation 1106 selects the compression function, which may be to select the parameter vector as described herein. Operation 1108 selects the quantization parameter. Note that the quantization parameter may be tied to the parameter vector, that is one is known from the other at both the sender and receiver, in which event there is no reason to send both to the receiver.

Operation 1110 represents compressing the data and operation 1112 represents quantizing the data. Operation 1114 represents transmitting the parameters and compressed data to the receiver.

Step 1202 represents receiving the compressed data and parameters, and step 1204 represents decompressing the compressed data. Step 1206 represents the quantizing the data, and step 1208 represents using the data in some way. For example, the data may be converted to analog for sending to a user equipment, or the data may be analyzed for estimating the channel.

One or more aspects, generally represented in FIG. 13, are generally directed towards transmitting, by a transmitter of a cellular base station device comprising an analog front end of a radio device coupled to a digital baseband processor of a central device, radio signal data to a receiver via a link Operations associated with the transmitting can comprise compressing (operation 1302), by the transmitter, radio signal data using a compression mapping function that is based on a parameter vector, resulting in compressed data and quantizing (operation 1304), by the transmitter, the compressed data based on a quantization parameter.

Transmitting the compressed data to the receiver can comprise transmitting the compressed data via a serial link or an IP network.

Further operations can comprise estimating a channel between the base station and a user equipment using reference signals originating from the central device. The compression mapping function that compresses the radio signal data can be a first compression mapping function, and the operations associated with the transmitting can comprise compressing, by the transmitter, the reference signals with a second compression mapping function having a higher resolution than a resolution of the first compression mapping function.

The handset 1600 can include a slot interface 1618 for accommodating a SIC (Subscriber Identity Component) in the form factor of a card Subscriber Identity Module (SIM) or universal SIM 1620, and interfacing the SIM card 1620 with the processor 1602. However, it is to be appreciated that the SIM card 1620 can be manufactured into the handset 1600, and updated by downloading data and software.

The handset 1600 can process IP data traffic through the communications component 1610 to accommodate IP traffic from an IP network such as, for example, the Internet, a corporate intranet, a home network, a person area network, etc., through an ISP or broadband cable provider. Thus, VoIP traffic can be utilized by the handset 1600 and IP-based multimedia content can be received in either an encoded or a decoded format.

A video processing component 1622 (e.g., a camera) can be provided for decoding encoded multimedia content. The video processing component 1622 can aid in facilitating the generation, editing, and sharing of video quotes. The handset 1600 also includes a power source 1624 in the form of batteries and/or an AC power subsystem, which power source 1624 can interface to an external power system or charging equipment (not shown) by a power I/O component 1626.

Computing devices typically include a variety of media, which can include computer-readable storage media or communications media, which two terms are used herein differently from one another as follows.

Computer-readable storage media can be any available storage media that can be accessed by the computer and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer-readable storage media can be implemented in connection with any method or technology for storage of information such as computer-readable instructions, program modules, structured data, or unstructured data. Computer-readable storage media can include, but are not limited to, random access memory (RAM), read only memory (ROM), electrically erasable programmable read only memory (EEPROM), flash memory or other memory technology, solid state drive (SSD) or other solid-state storage technology, compact disk read only memory (CD ROM), digital versatile disk (DVD), Blu-ray disc or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices or other tangible and/or non-transitory media which can be used to store desired information.

In an aspect, tangible media can include non-transitory media wherein the term “non-transitory” herein as may be applied to storage, memory or computer-readable media, is to be understood to exclude only propagating transitory signals per se as a modifier and does not relinquish coverage of all standard storage, memory or computer-readable media that are not only propagating transitory signals per se. For the avoidance of doubt, the term “computer-readable storage device” is used and defined herein to exclude transitory media. Computer-readable storage media can be accessed by one or more local or remote computing devices, e.g., via access requests, queries or other data retrieval protocols, for a variety of operations with respect to the information stored by the medium.

Communications media typically embody computer-readable instructions, data structures, program modules or other structured or unstructured data in a data signal such as a modulated data signal, e.g., a carrier wave or other transport mechanism, and includes any information delivery or transport media. The term “modulated data signal” or signals refers to a signal that has one or more of its characteristics set or changed in such a manner as to encode information in one or more signals. By way of example, and not limitation, communication media include wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media.

It can be noted that FIG. 17 describes software that acts as an intermediary between users and computer resources described in suitable operating environment 1700. Such software includes an operating system 1728. Operating system 1728, which can be stored on disk storage 1724, acts to control and allocate resources of computer system 1712. System applications 1730 take advantage of the management of resources by operating system 1728 through program modules 1732 and program data 1734 stored either in system memory 1716 or on disk storage 1724.

Interface port(s) 1738 include, for example, a serial port, a parallel port, a game port, a universal serial bus (USB), an infrared port, a Bluetooth port, an IP port, or a logical port associated with a wireless service, etc. Output device(s) 1740 and a move use some of the same type of ports as input device(s) 1736.

Thus, for example, a USB port can be used to provide input to computer 1712 and to output information from computer 1712 to an output device 1740. Output adapter 1742 is provided to illustrate that there are some output devices 1740 like monitors, speakers, and printers, among other output devices 1740, which use special adapters. Output adapters 1742 include, by way of illustration and not limitation, video and sound cards that provide means of connection between output device 1740 and system bus 1718. It should be noted that other devices and/or systems of devices provide both input and output capabilities such as remote computer(s) 1744.

Computer 1712 can operate in a networked environment using logical connections to one or more remote computers, such as remote computer(s) 1744.

The above description of illustrated embodiments of the subject disclosure, including what is described in the Abstract, is not intended to be exhaustive or to limit the disclosed embodiments to the precise forms disclosed. While specific embodiments and examples are described herein for illustrative purposes, various modifications are possible that are considered within the scope of such embodiments and examples, as those skilled in the relevant art can recognize.

In this regard, while the disclosed subject matter has been described in connection with various embodiments and corresponding Figures, where applicable, it is to be understood that other similar embodiments can be used or modifications and additions can be made to the described embodiments for performing the same, similar, alternative, or substitute function of the disclosed subject matter without deviating therefrom. Therefore, the disclosed subject matter should not be limited to any single embodiment described herein, but rather should be construed in breadth and scope in accordance with the appended claims below.

As it employed in the subject specification, the term “processor” can refer to substantially any computing processing unit or device comprising, but not limited to comprising, single-core processors; single-processors with software multithread execution capability; multi-core processors; multi-core processors with software multithread execution capability; multi-core processors with hardware multithread technology; parallel platforms; and parallel platforms with distributed shared memory.

Processors can exploit nano-scale architectures such as, but not limited to, molecular and quantum-dot based transistors, switches and gates, in order to optimize space usage or enhance performance of user equipment. A processor may also be implemented as a combination of computing processing units.

In the subject specification, terms such as “store,” “storage,” “data store,” data storage,” “database,” and substantially any other information storage component relevant to operation and functionality of a component, refer to “memory components,” or entities embodied in a “memory” or components comprising the memory. It will be appreciated that the memory components described herein can be either volatile memory or nonvolatile memory, or can include both volatile and nonvolatile memory.

As used in this application, the terms “component,” “system,” “platform,” “layer,” “selector,” “interface,” and the like are intended to refer to a computer-related entity or an entity related to an operational apparatus with one or more specific functionalities, wherein the entity can be either hardware, a combination of hardware and software, software, or software in execution. As an example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration and not limitation, both an application running on a server and the server can be a component. One or more components may reside within a process and/or thread of execution and a component may be localized on one computer and/or distributed between two or more computers. In addition, these components can execute from various computer readable media, device readable storage devices, or machine readable media having various data structures stored thereon. The components may communicate via local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network such as the Internet with other systems via the signal). As another example, a component can be an apparatus with specific functionality provided by mechanical parts operated by electric or electronic circuitry, which is operated by a software or firmware application executed by a processor, wherein the processor can be internal or external to the apparatus and executes at least a part of the software or firmware application. As yet another example, a component can be an apparatus that provides specific functionality through electronic components without mechanical parts, the electronic components can include a processor therein to execute software or firmware that confers at least in part the functionality of the electronic components.

In addition, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. Moreover, articles “a” and “an” as used in the subject specification and annexed drawings should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form.

Moreover, terms like “user equipment (UE),” “mobile station,” “mobile,” subscriber station,” “subscriber equipment,” “access terminal,” “terminal,” “handset,” and similar terminology, refer to a wireless device utilized by a subscriber or user of a wireless communication service to receive or convey data, control, voice, video, sound, gaming, or substantially any data-stream or signaling-stream. The foregoing terms are utilized interchangeably in the subject specification and related drawings. Likewise, the terms “access point (AP),” “base station,” “NodeB,” “evolved Node B (eNodeB),” “home Node B (HNB),” “home access point (HAP),” “cell device,” “sector,” “cell,” and the like, are utilized interchangeably in the subject application, and refer to a wireless network component or appliance that serves and receives data, control, voice, video, sound, gaming, or substantially any data-stream or signaling-stream to and from a set of subscriber stations or provider enabled devices. Data and signaling streams can include packetized or frame-based flows.

Additionally, the terms “core-network”, “core”, “core carrier network”, “carrier-side”, or similar terms can refer to components of a telecommunications network that typically provides some or all of aggregation, authentication, call control and switching, charging, service invocation, or gateways. Aggregation can refer to the highest level of aggregation in a service provider network wherein the next level in the hierarchy under the core nodes is the distribution networks and then the edge networks. UEs do not normally connect directly to the core networks of a large service provider but can be routed to the core by way of a switch or radio area network. Authentication can refer to determinations regarding whether the user requesting a service from the telecom network is authorized to do so within this network or not. Call control and switching can refer determinations related to the future course of a call stream across carrier equipment based on the call signal processing. Charging can be related to the collation and processing of charging data generated by various network nodes. Two common types of charging mechanisms found in present day networks can be prepaid charging and postpaid charging. Service invocation can occur based on some explicit action (e.g. call transfer) or implicitly (e.g., call waiting). It is to be noted that service “execution” may or may not be a core network functionality as third party network/nodes may take part in actual service execution. A gateway can be present in the core network to access other networks. Gateway functionality can be dependent on the type of the interface with another network.

Furthermore, the terms “user,” “subscriber,” “customer,” “consumer,” “prosumer,” “agent,” and the like are employed interchangeably throughout the subject specification, unless context warrants particular distinction(s) among the terms. It should be appreciated that such terms can refer to human entities or automated components (e.g., supported through artificial intelligence, as through a capacity to make inferences based on complex mathematical formalisms), that can provide simulated vision, sound recognition and so forth.

Aspects, features, or advantages of the subject matter can be exploited in substantially any, or any, wired, broadcast, wireless telecommunication, radio technology or network, or combinations thereof. Non-limiting examples of such technologies or networks include Geocast technology; broadcast technologies (e.g., sub-Hz, ELF, VLF, LF, MF, HF, VHF, UHF, SHF, THz broadcasts, etc.); Ethernet; X.25; powerline-type networking (e.g., PowerLine AV Ethernet, etc.); femto-cell technology; Wi-Fi; Worldwide Interoperability for Microwave Access (WiMAX); Enhanced General Packet Radio Service (Enhanced GPRS); Third Generation Partnership Project (3GPP or 3G) Long Term Evolution (LTE); 3GPP Universal Mobile Telecommunications System (UMTS) or 3GPP UMTS; Third Generation Partnership Project 2 (3GPP2) Ultra Mobile Broadband (UMB); High Speed Packet Access (HSPA); High Speed Downlink Packet Access (HSDPA); High Speed Uplink Packet Access (HSUPA); GSM Enhanced Data Rates for GSM Evolution (EDGE) Radio Access Network (RAN) or GERAN; UMTS Terrestrial Radio Access Network (UTRAN); or LTE Advanced.
